It doesnt work on any Windows 7 Ultimate 64bit in my home but it does work on my laptop with Windows XP Professional, and it worked with RC1 (build 7100) of Windows 7 ultimate on the exact same machine about 2 weeks ago. The only logical conclusion is that it is software related but seeing as it doesnt get to actually using the device the conclusion I draw is that windows has some incompatibility with something related to this kind of device (very specisfic I know, but this is what Im trying to figure out). This problem is also not device specific as the other modem I have tried is not the same model. As for power from the USB ports I have tried about 8 different ports on 2 different machines (one Asus MB the other a ASRock), same problem. Any other ideas?\
(Additional thought: I was hoping the fix on the Vodacom site would fix the way Windows tries to detect these devices, and that would be the problem. But alas, no joy!
Its definately a windows inf driver missing. I noticed that a fresh clean install works until a windows update is done. I did a system restore on all the machines i had and the modem works. . I will try find exactly which part of the updates screws up the modem drivers. mayb do selective updates?
